How to loop through a LinkedIn API response? - php

Question

I am retrieving connections via LinkedIn's API.
This is a sample of the response. All I want to do is loop through this using PHP, accessing first and last names. Should be simple, but I am stumped. Thanks.

Answer 1

What you have as the response is an stdclass which will have all of its properties public.
This is how you iterate it:
$response = $this->getResponseFromLinkedIn();
foreach ($response->values as $value) {
$firstName = $value->firstName;
$lastName = $value->lastName;
// do something with the extracted values!
}
